incoming phone call connection issues

A few weeks ago, my tv service went down. The technician discovered a faulty cable amplifier and removed it. A few days later, a new service line was installed. I seem to have no problem with tv or internet, but I am experiencing some phone connection issues. Usually, it occurs when someone tries to call me. My phone rings, I see the number on caller id, but when I answer the line clicks and goes dead. When the party calls back, they tell me that the phone rang, but then went to a fast busy signal in their earpiece. This is now happening at least 8-10 times per day. Occasionally when I make a call out, the other party answers but I cannot hear them and they cannot hear me. This is intermittent, but annoying none the less. Is it possible that I need an amplifier reinstalled on the line, or is there some other issue causing this?

Re: incoming phone call connection issues

It is doubtful that it is RF signal related. I would look more into the inside phone wiring in the home with a short, wiring fault or corroded phone jack, bad cords or failing telephones.

To confirm where the issue is, first reset the eMTA telephony modem. There is a small indented button on the panel where the cables attach. Give it a push for a few seconds, you will need a toothpick or some poker.

Then, take a known good wired telephone and connect it directly to the L1/L2 jack on the eMTA telephony modem and give it a good test for a few days. If it is working normally, then it is a inside phone wiring issue which will need a going over. You can try and troubleshoot it yourself, hire a local low voltage contractor, or get a Comcast tech to fix it.

If your issue still happens with the phone connected directly to the eMTA, then contact Comcast support, and they will need to send out a tech.
